Abstract

A composition comprises at least one form of attapulgite present in a solid weight fraction amount ranging from 0.25% to 5%; kaolin present in a solid weight fraction amount ranging from 17% to 50%; and optionally Ball Clay in a solid weight fraction amount ranging from 0% to 25%. Although makeable by other processes, in some embodiments, the composition is makeable by mixing component ingredients. Although usable for other purposes, in some embodiments, the composition is used to make ceramic pieces, e.g., via casting, pressing, jiggering or jollying, especially when the slip has solids, chemistry and viscosity suitable for shaping before drying, sintering, and optionally finishing.

Description

FIELD

[0001] A composition which comprises at least one form of attapulgite present in a solid weight fraction amount ranging from 0.25% to 5%; kaolin present in a solid weight fraction amount ranging from 17% to 50%; and optionally Ball Clay in a solid weight fraction amount ranging from 0% to 25%. Although makeable by other processes, in some embodiments, the composition is makeable by mixing component ingredients. Although usable for other purposes, in some embodiments, the composition is used to make ceramic pieces, e.g., via casting, pressing, jiggering or jollying, especially when the ceramic formulation has solids, chemistry and viscosity suitable for shaping before drying, sintering, and optionally finishing.

[0002] A composition, in the form of powder(s), granules or prills; or in the form of a slurry; or in the form of a paste or filter cake that can be used to prepare a suspension, slip, or a pug which can be cast, pressed, jiggered or jollied into ceramic pieces, containing ...
